Hi, i have a Voodoo 5 5500 AGP and he are installed on Asrock M266A, according this site http://www.pcgameshardware.de/3dfx-Voodoo-Har … Special-1246582( this Motherboard is fully compatible.
I have a problem: My V5 don't work with dual chip. I receive the imagem bellow where i start everything 3D game (Glide, OGL or D3D, inclusive in DXDIAG test). If i configure to use some one chip, all start correctly.
I find a damaged capacitor (470uF), probably was damaged on transport. Yours pad have been broken, and i replace then (provisionally ) by one PTH capacitor of same value.
A curious behavior in input power rail is this ripple. I found this ripple on 5V and 12V, and this appear even i connect my bench powersupply... This ripple is normal? For me, is no normal and suggest another broken capacitor...
The voltage signal after filter step on diodes located at the botton of the PCB are FLAT in 3.02V.
Do I have a damaged VSA100?
I have tested with Windows 98 and Raziel Driver and the last 3dfx oficial driver. The problem also occurs in WinXP with Amigamerlin and SFFT last drivers.
Does anyone have a schematic for maintaining this board?
